To all. whom 'it may concern:

Be it known that I, SrLAs E. BAILOR, a citien of the United States, residing at rllarkio, in the county of Atchison and State of Missouri, have invented a new and useful Cultivator, of which the following is a specification.

The invention .relates to improvements in cultivators.

The object of the present invention is to improve the construction of cultivators, more especially the means for controlling the gangs of cultivating devices for enabling the same to be raised and lowered to arrange the plows for operating at the desired depth.

A further object of the invention is to provide an adjusting device capable of enabling the members of each gang of plows to be raised and lowered both simultaneouslyT and independently with a single operating lever and of automatically-locking one of the niembers in its adjustment, .when the adjusting means is4 set for raising and lowering the other member.

1 Another object of the invention is to prowith this invention.

vide simple and efficient means for adjusting the gangs of plows toward and ,from each other, and for swinging the same laterally simultaneously with the carrying wheels for turning the machine. Also the invention has for its object to enable the gangs of plows and the carrying wheels to be shifted laterally either by hand, or foot in guiding the machine.

With these and other objects in view, the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended; it'being'understood that .various changes in the form, proportion, size and minor details of construction, within the scope of the clai'ms, may be resorted to withf out departing from the spirit or sacrificing any of the advantages'of the invention.

The' hangers'Q/lf-are mounted at` their rearsides 'Y or ends in bearing brackets 23, arranged ver- `f ets 23.

tically and'secured tothe'front bar or member'of the axletree, and providedat the top andbottomjvith vertically alined bearings 24, consisting of'forwardly projecting perforatedlugs 1or ears through which pass the rear pivots 22 of the hangers` The hangers *are* arranged in pairs, the membersl of each Vpair rbeing parallel, and they are adapted tov swinglaterally of the machine to ,carryrthe` 'connecting arches and the gangs of plow beams thereof toward and from each other, and the members of eachvpair .of hangers maintain their parallel relation in all the adjustnfientsy of the gangs ofk plows. -Each hanger is braced b an inclined rod 25, extending I downwar ly and forwardly' from the 'upper end of the rear pivot 22 of the hanger. td the lower end of the front vertical pivot 2O of the same. The uppor ends of-the `rear pivots are provided "with adjustable forwardly and upwardly from thelower ends of the rear pivots to the frame bar 11 and are'boltedl, or otherwise secured to the same.

The eyes 28 at the lower ends of the sides of the V-shaped braces'are'interposed between the lower ears of the bearing brackets and thel bottom connecting portions of the' vhan ers.

T e inner and outer plowbeamsof each gang of plows are connected by links or rods y29 with arms 30 and 31, which extend forwardlv froma transversely disposed rock shaft u32.l The .links or rods 29 pass through perforationsof L-shaped'il brackets or plates 33 of the plow beams, and they have upper on them for yieldably connecting the vplow with the arms 30 andl 31. Thelower springs yieldably support the plow, and thereby cushion the connections in raising the lows,

and lower spiral springs 34 and 35 disposed and the upper springs operate to yie dably ,hold the plows in the ground.

Each f rock shaft is, journaled in suitabley bearings and is supported by inner and Aouter laterally movable bars or members 36-and 37, extending longitudinallyT of the machine and provided at their front endswith verti- -ca`l bearing eyes 38, which are secured on the upper ends of the front pivots 20 by means of upper and lower collars 9. The. upper and lower collars are y.provided with set 'screyvs 40, and adjustablysu port andretain the bearing bars ,or mem ers -37'on the front pivots of the hangers. The bearing bars 36 Aand'37, which are connected at their pivoted at their front ends to the hangers 21,

are maintained in parallelism and are adapted .e to be shifted or moved transversely of the machine in adjusting the gangs of plows toward and from each other.

The inner and outer armsv are loose and fast, respectively, with relation to the rock shaft 32, the outer4 arm 31 being fixed to the shaft by means of a set screw 41.- The inner arm 30 is provided at its inner or rear end with an eye or sleeve 42 to receive the rock shaft 32, and4 it is provided with an upwardly and :rearwardly extending sector-shaped plate or member 43, preferably cast integral with the arm 30, but it may be rigidly connected with the' said arm 30 in any other preferred manner. The shaft 32 also carries a similar sector-shaped plate or member 44, and these two plates or members 43 and 44, which are spaced apart and which correspond roo Vrear ends by the rock shaft 32 and which vare e with the arms 30 and 31, are loose and fast,

lrespectively, withrelation to the shaft 32, fthe sector-shaped plate or member 44 bemg fixed to the shaft by means of a set screw 45, or other suitable fastening means. Each of these sector-shaped plates or members is proratchetbpenings-46 and 47, adapted to be engaged by the means hereinafter described,

.vided with -inner and outer arcuate series of u A65 central'position, illustrated in Fig.`5

able on-the shaft 32 and slidably connected.

with the inner bearing bar, which isv provided with a guide or loop 49 for holding the shiftable locking device against rotary movement. The shiftable locking device is composed of two sides 50 and a connecting loop 51, consisting of two side. portions and a transverse' connecting portion, which .pass

- through the guide 49 of the inner bearing bar 36. -The sides 50 of the shiftable locking device 48 are provided at their lower ends with bearing openings or eyes 52, through which the shaft 32 y asses, and the said sides are provided at t eir upper ends withinwardly extending lugs or projections 53, preferably arranged in sets of three, but one or more may be employed, asiwill be readily understood. When the locking device 48 is in a central position, as illustrated in. Fig. 5 of the accompanying drawings, the lugs orprojec- 30 tions 53 of the said device 48 are located beyond and vare out of engagement with the sector-shaped plates or members 43 and 44. Any lateralmovement of the locking device from this position will carry one set of lugs or `35 projections into engagement with one of the sector-shaped plates or members, and will move the other set of lugs or projections outwardly from the other plate or member, as vclearly illustrated in. Figs. 6 and 7 of the accompanying drawings. This movement of the. shiftable locking device 48 is effected through aslidable detent 5 4, which releases the sector-shaped plate or member, that is engaged by the locking device. The detent 54,. which is in the form of a rectangular block .or piece, is provided `at its ends with projecting fingers or lugs 55, located at opposite sides of the adjusting device and preferably arranged in sets of three to correspond with the lugs or projections 53 ofr the shiftable locking device. When the detent 54 is in a central position, as illustrated in Fig. 5

ofthe accompanying drawings, the fingers 55A are in engagement with each of the sectorshaped plates or members, and their outer terminals bear 'against the locking device, and positively maintain the same out of engagement with the sector-shaped plates or members. The sides of the locking device are provided with arcuate braces 56, presenting arcuate faces to the'ends of the fingers 55 of the detent 54 and enabling the said fin@ rs t'ol slide freely on the side portions Vo the locking device. When the detenft 54 is .fthe

f` the drawings, the fingers 55 extend through both of the arcuate plates or members and their' 4outer ends engage the side portions of the locking device and maintain the lugs or'proj ections thereof positively out of engagement with-the sector-shaped platesor members, and when thedetentis moved from the central position, shown in Fig. 5, to either of the, side positions, illustrated in Figs. 6 and 7, it does not release either of the sector-shaped 75 plates or members,'until such plate or member is engaged by one ofthe sides of the shiftable locking device, so that when it is desired to adjust one of the plows .of either gan-g, there is no liability of affecting the ad'- 80 "justment of the other plow of such gang. The

braces 56 of the sides of the shiftable locking device 48 are connected at their lower ends with the sides 50 of the locking device by short bottom portions, as clearly illustrated in Fig. 10 of the drawings.

The detent 54 is slidable in spaced guides 57 of anl operating lever 58, which has a forked or bifurcated lower portion for straddling .a centrally arranged toothedV ratchet member 59 of sector-form, as clearly illustrated in Fig. 8 of thedrawings. The lower ends of the sides of the forked portion of the operating lever are provided with suitable bearlng openings for the shaft`32, and the upper ends 60 of the said sides' are bolted,

or otherwise secured to the lever, but they may be formed integral with the same, as

-will be readily understood. The toothed ratchet plate or member 59 is provided with' 100 a bearing eye or'sleeve 6l for the reception of the shaft 32, and it has a dependin lug or flange 62, to which the rear end o the inner bearing bar 36 is bolted, or otherwise secured, whereby the' central ratchet plate l105 or member 59 i's vheld against rotary movement and a support provided for the adjacent end of the shaft 32. Theguides 57 are provided withjoblong openings to receive the end portions of the detent 54, which is provided with a central slot 6 3 for a crank arm 64 of a shaft 65. Tlhe shaft 65, which i? `ournaled in u er and ower bearin s 66 o Jthe lever 58, provided at its upmwith a substantially U-shaped portion, thewll upper side 67 'of which constitutes a grip or handle. The grip or handle 67 of the crank. shaft 65 constitutes the handle of Vthe operating lever, and it is adapted to be grasped by the operator `for enabling the operating lever 58 vto be swung. backwardlyv or forwardly, and it is also capableof a lateral oscillatory movement tov roc k the shaft 65 for moving the detent 54 to any of its several positions. The operating levery 58 is locked A125 at any nadjustmen't by means of a springactuated pawl or dog 68, suitably mounted on the-lever and arranged to en ager the central ratc'het member 59, as clear y illustrated in Fig. 8 o f the drawings. The4 pawl or dog .130

' mounted stood.

is connected by a wire. 69, or other suitable means, with a latch lever 70, pivotally portion thereof and provided with an arm, forming a grip or handle and arranged to be grasped simultaneously with the grip or .handle by the crank,shaftv 65. The latter lever 70 is of bell crank form and its otherv arm isconnected with the wire 69. By this construction, the operating lever may be readily released or locked and may. be instantly. connected with either or vboth of the 'sector-shaped plates o'r members 43' and 44,

and when it is moved into engagement with only one of such plates. or members 43 and 44, the other plate or member -is automatically locked and 'retained in its adjusting position..4

The inner' bearing bars 36 are connected with upper and lower transversely disposed I rack bars 71 and 7 2, provided at their outer ends with. upwardly extending arms .73 and 74, havingjopenings 75 for the reception ofy the bearing 71- is providedat its lower edge .with teeth,

bars. The upper rack bar which meshes with a pinion 7 6, and the latter also meshes with the teeth of the lower rack -bar 7 2, which has ,its teeth at its upper edge, as clearly illustrated in 1 3 of the drawings. The" toothed portions of the rack bars, which are spaced apart and are arranged in parallelism with each other, extend through a substantially U-sha'ped guide 77, consisting of a pair of guiding arms 78- The.

and a bottom connecting portion.

guiding arms 78 are provided-with openings through which the rack'bars pass, and the guide 77 is thereby supported by the rack ars. I v

The pinion 76,' which is provided with hub extensions 79, is journaled in bearing openings of a pair of plates S0, secured to the bottom connecting portion of the guide 77 at the center thereofl and extending upwardly therefrom, as clearly illustrated in Figs. 1l and -13 of the drawings. lVhen the pinion is rotated, the rack bars will beactuated and their upwardly extending arms 73 and 74 will be moved toward 4and from each other to adjust the'gangs of plowslaterally of the machine. When the'rack bars are adjusted, the hangers will be swung laterally, and the means for raising and lowering their adjustment, as will be readily under- The pinion 79 is provided with an oppositely flared opening 81, having grooves 32 for the reception of 'tapering ribs or keys 83 of an inclined operating shaft S4, which extends through the'pinion, and which is capable of both rotary and lateral movement to adjust the gangs of vplow beams. The inclined -cpc-grating shaft is provided near its .1 weer end with a substantially semi-spherical on the crank shaft at the handlev rotary arranged'in a socket 86 of a bracket 87, and the latter depends from the transverse frame bar 11 at the centerl thereof. The semi-spherical`head85of the in c'lined operating shaft is provided withI suitable projections or teeth l88, ,which are adapted to engage correspondin groovesv or re cesses 89 of the bottom "o' the l socket 36, whereby the head ofthe inclined o erfatin shaft is operated with the socket an is hel against rotary movement. The inclined operating shaft is retained in its interlocked relation with the socket by lmeans of a coiled s ring i90, disposed on the lower portion of tlie shaft and interposed betweenthe socket 86 and -anut 91, but'v any other suitable means may be provided for locking the shaft against movement. Thespring yieldably holds the head 85 of the inchned shaft inenhead 85, which is the head to bei drawn from engagement with the socketby a llongitudinal movement of the inchned "shaft for rotating the latter. -The inclined operating ,shaft is providedat its u per or rear end with a suitable grip or rotated to operate the rack bars, and it is also capable of being oscillated to shift the transverse bar 9 and the angs of plows, as hereinafter explained. T ie opening' 93 of the bottom socket 86is sufficiently large to permitthe inclined shaft to be oscillated for movin the carrying wheels and the gangs of plowsV aterally in changing the direction of the machine. c-

the flaring of` the opening ofthe inion facilitate the oscillatory movement ofp the inclined operating shaft, a the latterpasses through a vertical guide^94 of the shiftable bar 9 for 'connecting the lattery to the shaft. The guide 94 is in the form of a loop, which permits the inclined operating shaft t'o be raised and lowered to disengage it from and to engage it with a ratchet 95. The ratchet 9 5, which is adapted to hold the inclinedoperating shaft against lateral movement, consists of a plate or member centrally. secured between the bars or members of the axletree and extending upwardly and downwardly therefrom, the upwardly extending portion being provided with a horizontal series of teeth, forming intervening spaces or recesses to receive the inclined operating shaft.

The inclined shaft, which operates' in the nature of a lever, enables the gangs of plows In' this adjustment of the to be arranged at different angles'with veia.-

gagement with the socket 86, vand it permits The oppositely tapered ribs or -keys 83 and l yand the'carrying wheels to be shifted laterwhich hinged connections permit the hangersv han e 92', and it is adapted to be partially plow beamsl and the means for ist suitable bearing 99 of a bracket 100, and supported at its rear end 101 by the depending .portion of the ratchet plate or member 95.

The depending portion of the ratchet plate. or member 95 is provided with abearing opening for the crank shaft 98, which has its rear end reduced to form a journaland to provide a shoulder for engaging the lower portion of the ratchet plate or member.

The bracket 100, which is composed of two sides and a central connecting portion, is secured to and depends from horizontal seat supporting bars 102, which are supported at an intermediate point by the axletree. The front ends 103 of the seat supporting bars are secured to `hanger plates or.

knees, which are bolted, or otherwise secured to the transverse frame bar 11, as clearly illustrated in Fig. 4 of the drawings.

The crank shaft 98 is provided with laterally extending arms 104, which are connected by links 105 with treadles or foot levers 106, pivoted at their front ends to the lower terminalsof the sides of the bracket 100 and provided at their rear ends with suitable plates for the accommodation of the vfeet of the driver. When either of the ,treadles orz foot levers .106 is depressed, the rock shaft 98 will be partially rotated, and the crank arm 97 will shift the transversely disposed bar or member 9v in one direction or the other'. This will change the direction of the carrying wheels, and as the gangs of plows are connected with the shiftable bar or member 9 through the inclined operating shaft, they will be shifted simultaneously with the carrying wheels. In changing the direction of the machine, it is necessary to disengage the rear portion of the inclined operating shaft from the ratchet member.l 95 to permit the said shaft to swing laterally.
